From ERA brand in China, ASTM F439 can be applied to hot and cold water pipes in sizes from 1/2 "to 6".n1. Sturdy: Since PVC-C is stronger than PP-R, PB and PEX, it requires fewer hooks and brackets. PVC-C can withstand greater pressure. At the same flow rate, compared with PP-R, PB and PEX pipes, PVC-C pipes can use smaller diameters. 2. Easy to install: It can be connected using special fusing agent, and no special tools are needed during installation. It is suitable for both surface and concealed installation. 3. Corrosion resistance: PVC-C is not easily permeable to oxygen, so the metal parts in the system will not corrode due to oxidation. 4. Good flame retardancy: The oxygen index of PVC-C is 60, its combustion ability is very low, it extinguishes immediately after leaving the fire, will not produce fire droplets, and can suppress the generation of smoke and toxic gases. 5. Not affected by residual water: Unlike polyhydrocarbon pipes, PVC-C pipes are not affected by residual water and will not crack or collapse after long-term use. 6. Alkali resistance: PVC-C has strong anti-corrosion ability against both alkali and alkali, and can be used to transport HCL and NaOH liquids.
